I'm new to the forum but would like to try nested virtualization. I have an
AMD-based system at home&  Intel-based systems at work.

Would appreciate if you could give me some pointers as to how I can start.

1. Install a standard Xen setup.
2. Set up a HVM guest (must be either a Linux or NetBSD guest)
3. Configure the HVM guest as a Dom0
4. add nestedhvm=1 to your guest config file
5. Set up a HVM guest within your HVM guest
6. Have fun

If you encounter a problem that the Dom0 hangs at boot in step 3 then
disable the TSC Deadline Timer in libxc/xc_cpuid_x86.c
